Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin
Can I change gravel without removing fish?

Am I asking for problems if I attempt this? Would I be better off going with root tabs and keeping my current gravel?
I have 3 quarters of a 25l bag of manado under the stairs and want to add plants to that tank to change it's look as it's the display tank.

I probably could have avoided it by doing a big water change

Im thinking of doing something similar, ive way to much sand/gravel in my tank and want to remove 3inchs of it. I read online that by disturbing substrate toxic gases are released, any body else know about this?
hydrogen sulphide is what they're usually talking about. It tend to only be a big problem if the substrate is quite deeps and esp if it's very fine i.e. no oxygenated water reaches it. then anaerobic bacteria flourish and hydrogen sulphide is a result. if you remove too much substrate in one go you risk losing a lot of good bacteria in one go and the colony in your filter will have a hard time keeping up for a while. but you may also risk releasing a lot of hydrogen sulphide in one go too. if it's released into the water in small doses, the fish are usually fine but larger sudden releases can be fatal... and sometimes instantaneously.

Where the tongue slips, it speaks the truth.
A life making mistakes is not only more honourable, but more useful than a life spent doing nothing at all.

This way you will have to remove it in stages or you will remove to much water in one go.
Also any hydrogen sulphide will be released in the syphon hose and not in the tank.

..it is do-able
..I've done it
..I wouldn't do it again.
It is much more messy than just to empty the tank, take everything out and then
get the gravel and substrate in proper way.
I am planted!
